Methods BMSCs were obtained from femurs of Long-Evan rats and dealt with 0.85 NH4Cl. The cell growth curve and cell cycle were measured and surface antigens were detected by flow cytometry. Osteoblast differentiation was studied by Alizarin red staining. Results BMSCs had active proliferative ability. The growth velocity of passage 5 cells was slower than that of passage 3 cells. The cell cycle analysis showed that 93.79 of BMSCs was at G0/G1 phase. BMSCs were positive for CD29 and CD44, but negative for CD45. Alizarin red staining of BMSCs after osteoblast induction was positive. Conclusion Highly purified BMSCs obtained from Long-Evan rats by 0.85 NH4Cl show stable biological properties.

Objective To discuss the effectiveness of community-based intensified health management on type Ⅱ diabetes patients.Metbods From June 2010 to December 2011,1 024 type Ⅱ diabetes patients in Mishi Lane community were enrolled and assigned to the intervention group (n=501,obtaining intensive health management) and the control group (n=523,obtaining routine community health management).Fastingbloodglucose (FBG),2-hour postprandial blood glucose (PBG2h),HbA1c,blood pressure (BP),triglyceride (TG) and body mass index (BMI) were tested and recorded before and after the intervention.Student's t test or Chi-square test were used for data analysis.Results Differences of age (t=0.124,P＞0.05) and gender (x2=2.0,P＞0.05) were not statistically significant (both P＞0.05).Following the intensive health management,the control rates of HbA1c,BP,TG and BMI were increased to 75.4％,30.4％,85.6％ and 49.0％,respectively (x2 values were 4.54,4.71,6.54 and 3.67; all P＜0.05).TG,FBG and PBG2h of the intervention group were (1.5 ± 0.9),(6.2 ± 1.3) and (8.3 ± 2.4) mmol/L,respectively,which were significantly lower than those of the control group (all P＜0.05).Conclusion Community-based intensive health management could be effective for diabetes patients.

Powder X-ray diffraction (PXRD) technology combined with cluster analysis method was used to classify 75 batches of crystalline ceftriaxone sodium into subtypes, the crystalline characteristics of each subtype were measured with scanning electron microscope (SEM). By comparing some parameters of these subtypes correlated to crystallization process of ceftriaxone sodium, such as salification rate, water content in different subtypes, as well as by studying different lattice stabilities, different compatibilities with rubber closures during accelerated stability tests, the key point to improve the quality of domestic ceftriaxone sodium was disclosed. The results of this paper indicated that the fine structure of the products could be controlled well by improving the salification and crystallization process. As a result, the subtype II of ceftriaxone sodium with high stability can be produced.

Objective To discuss the effectiveness of knowledge-attitude-practice(KAP)-based health management on type 2 diabetes in community residents.Methods From June 2010 to December 2011,930 type 2 diabetes patients living in Mishi Lane Community were enrolled and assigned to the intervention group(n=494) and the control group(n=436).The KAP mode was used for the intervention group,and the routine management mode was applied to the control group.Fasting blood glucose(FBG),PBG2 h,HbAlc,blood pressure(BP),triglyceride(TG) and body mass index(BMI) were tested and recorded.Student's t test or Chi-square test was used for data analysis.Results Age(t=0.124,P＞0.05),gender(x2=2.0,P＞0.05) and other demographics showed no statistically significant difference between the two groups(all P＞0.05).After one-year KAP-based health management,HbA 1 c of the intervention group reduced to(6.1 ± 1.2)％,FBG and PBG2 h reduced by 1.7 and 3.23 mmol/L,respectively(t=4.926,P＜0.05; t=4.306,P＜0.05; t=4.523,P＜ 0.05).Diet,physical exercises,medication,regular inspection,unhealthy habits and questionare test awaveness of the intervention group were improved(86.03％,82.19％,85.63％,70.45％ 76.11％ and 88.46％,respectively.Drinking,dietary structure,overweight and physical exercises of the intervention group were also improved(14.17％,15.79％,70.65％ and 68.83％,respectively; all P＜0.001).Conclusion The KAPbased health management is proved to be effective in the control of community diabetic patients.

Objective To investigate the effective endodontic irrigation protocols on smear layer removal from curved canals. Methods Forty extracted mandibular first molars with curved mesial root canal were selected and decoronat-ed. Mesiobuccal root canal was instrumented to F3 using handed ProTaper system, and randomly divided into four groups ac-cording to final irrigation protocols: syringe irrigation (group A), #30K file agitation (group B), passive ultrasonic irrigation (PUI, group C) and combination of #30K file agitation and PUI (group D). The ultrasonic file was located within 0.5 mm coro-nal from start of the curvature. All root canals were mesio-distally split, snicked at the start of the curvature and 2 mm apical-ly from the start of the curvature, and divided into three sections. They wereⅠ,ⅡandⅢfrom coronal to apical. The smear layer of each section of root canal was examined under scanning electron microscope (SEM). Results Group D presented small amounts of scattered or thin smear layers and obtained the lowest score at each section of root canal wall. At sectionⅠandⅡ, there was no significant difference in smear layer score between group D and group C. The smear layer scores were both significantly lower in group D and group C than those of group A and group B (P<0.05). At sectionⅢ, the smear layer score was significantly lower in group D than that of group A, group B and group C, and which was significantly lower in group B and group C than that of group A (P<0.05). Conclusion When ultrasonic file was located coronal from the start of the curvature, K file, which was the same size as dimension of apical portion preparation to agitate and PUI can remove smear layer from curved canals efficiently.

Objective To evaluate the effects of calcitonin and 1, 25 vitamin D on the bone loss in experimental periodontitis in rats. Methods A total of 125 male Wistar rats were randomly allocated to five groups according to the treatments during 8 weeks: normal control (group A, n=25), periodontitis(group B, n=25), calcitonin (group C, prepared in sterile saline at 2 mg/L, and 2μg/kg was administered daily, s.c. , n=25), 1,25 vitamin D (group D, prepared in corn oil daily at a concentration of 2 mg/L, and 2μg/kg was administered daily, p.o. , n=25), 1,25 vitamin D plus calcitonin (group E, n=25). The experimental model of periodontitis was induced by ligating floss around mandibular first molars with orthodontic wires in B,C,D and E groups. Five rats from each group were sacrificed, and the specimens were prepared at 2, 4, 6 and 8-week. The probing depth (PD) and alveolar bone level were observed. The serum bone-specific alkaline phosphatase (BALP) and osteocalcin (OC) were measured by enzyme-linked immunosorbent assay (ELISA) at 8-week in each group. Results The values of PD were significantly lower after 4, 6 and 8 weeks in E group than those of B, C and D groups (P＜0.05). The alveolar bone loss was significantly lower after 6 and 8 weeks in group E compared with that of B, C and D groups (P＜0.05). The serum levels of BALP and OC were significantly higher after 8 weeks in E group than those of B, C and D groups (P＜0.05). Conclusion The present study suggests that 1, 25 vitamin D and calcitonin can partially inhibit the alveolar bone loss induced by periodontitis. Especially, the application of both is more effective than either drug treatment alone.

Objective To screen primers used in polymerase chain reaction (PCR) for detecting Trichomonas vaginalis. Methods Three pairs of PCR primer reported in the literatures (TVA5-TVA6, TV1-TV2 and TVK3-TVK7) were screened. For each PCR, four components, including primers, Mg2+, dNTPs and Taq polymerase, were optimized using Taguchi methods to determine the optimal PCR conditions. With the optimal conditions, the sensitivities of three PCR were compared. Vaginal swabs were collected to detect Trichomonas vaginalis by culture and PCR, and the PCR with highest sensitivity was evaluated. Results All three PCR were of high specificity, and the PCR with primers of TVK3-TVK7 had the highest sensitivity. Of 25 clinical vaginal swabs, T. vaginalis was detected in 7 samples by the culture, however, it was detected in 8 samples by the PCR. All culture-positive samples were also positive by PCR. Conclusions The PCR with the primers of TVK3-TVK7 is highly sensitive and specific, which could be useful to detect T. vaginalis in vaginal swab samples.
